Create MCQA for Object literal

[kirandash]

Please create an MCQA to be added as question number 34.

The multiple choice question should be on the topic "Object literal". The difficulty level should be "Medium/Hard"

Tasks:

• [x] add your code to 034 folder under code
• [x] add your question to 34 in README.md file
• [ ] create a video explanation and upload on YouTube (optional)

Explanation:

• There are many ways to create an object
  • class Object is one way
• Object allows us to create a container to put multiple data type. It's a key value data structure
• Object has properties and methods

Sample interview question for inspiration

• Can you have dynamic keys with object literal?
  • yes, const tv = "pCode"; let obj3 = { [tv]: 1001 }
• How can you add read-only properties to an object? (Level: Hard, since most devs can't answer this)
  • Object.defineProperty() and Object.create()
• What is property value short hand with object literal? let obj = { pCode, pName } : ES6
• What will be the output of this code? Explain the reason why?

  let obj={a:'First'};
  let obj1 = obj;
  obj1.a="Second";
  console.log(obj.a);

  • ans: "Second", since Object assigned with = have same reference
• How can we create a clone or separate copy of an object literal?
  • let obj1 = Object.assign({}, obj2) or let obj1 = {...obj2}
